Q. My Pug's nose is red and he doesn't have a yeast infection. He is taking medicine for that. It seems to get worse when he goes outside. Any ideas?
JESSICA L DESROSIERS
A. Redness or irritation can be caused by a number of things including yeast infections as you mentioned, but can also be caused by allergies to the environment, or even cold or hot weather. Dogs with short fur can often get sunburns on the skin, and the cold may also irritate or cause redness when outdoors. Allergies to pollens or other outdoor allergens may also cause redness on the body or nose. An allergy medication from your vet is usually all that is needed to clear this up.
If the redness is happening just when outside, it may also be that your dog is digging or nosing around in something that is irritating. It may be a good idea to watch your dog a few times while he is outside to see if there is anything he enjoys exploring. The redness could just be irritation from that.
However, if you are concerned about the redness, it is always a good idea to bring it up with your veterinarian to make sure there is not a more serious cause behind it.
